1 Before testing
1.1 Preparing for the test
• Fit the AccuScreen PRO with a charged battery pack.
• Plug the probe lead into the socket on top of the AccuScreen PRO. Align the red dot on the
probe plug with the red dot on the socket.
• For ABR testing also plug the electrode cable into the ABR plug.
• For ABR testing the probe can be replaced by the Y-cable with Ear Couplers. A major advantage
in using the Y-cable is that once the test starts, both ears will be tested consecutively.
• Plug the Y-cable plug into the "Ear probe" socket on top of the AccuScreen PRO. Align the white
dot on the probe plug with the red dot above the socket of the AccuScreen PRO.
• The patient data can be entered in the AccuScreen PRO directly or in the AccuLink and then be
transferred to the AccuScreen PRO. To do so, see “From a PC to AccuScreen PRO” on page 22
Note · If this is the first test of the day, switch on the AccuScreen PRO and make a probe test: Fit the probe
in the probe cavity and select Options > Self test > Probe test.
Note · For details on settings and how to use the AccuScreen PRO see the AccuScreen PRO User Manual.

Before testing - Preparing the test environment 12
1.2 Preparing the test environment
• Make sure that the test environment is as quiet as possible.
• Be sure to follow any established infection control procedures for the setting in which you are
working.
• Always use clean eartips.
• Swab the probe tip with disinfectant between babies.
1.3 Preparing the patient
• To prepare the patient for testing, position the patient so that you can easily access the ear to be
tested.
Neonatal screening • Neonatal screening is best performed when the baby is sleeping. If required, swaddle newborn
babies before ABR testing for a calming effect.
• Grasp the pinna and gently pull back and slightly away from the patient's head.
• Look into the ear canal to check for vernix or debris. Clean the ear canal, if required.
• Because newborn ear canals are very soft, they are easily pressed out of shape. If this is the case,
wait until the ear canal returns to its original shape.
